DUMPING WAGON.

SPECIFICATION forming part of Letters Patent No. 688,829, dated December 17, 1901.

Application filed May 20, 1901.

To roZZ whont it may concern.- 7

Be it known that I, MAURICE M. COLLINS, a citizen of the United States, and a resident of Goodison, Oakland county, State of Michigan, have invented certain new and usefulImprovements in Dumping-Wagons; and my preferred manner of carrying out the invention is set forth in the following full, clear, and exactdescriptiomterminatingwith claims particularly specifying the novelty.

This invention relates to wagons, more especially to that class which dump; and the object of the same is to produce improvements in dumping-wagons of that type having a sectional bottom whose various sections or members are pivoted and adapted to be operated simultaneously. t

The present invention consists in the details of construction as fully described hereinafter and as shown in the drawings,wherein Figure I is a side elevation of this wagon with its bottom closed, showing in dotted lines the position of parts when dumped. Fig. II is a central longitudinal section with the bottom dumped. Fig. III is a cross-section through a pair of the supporting-eyes. Fig. IV is a detail view showing the bail for moving the lock, one side of the bar, and one of the links and its roller.

In the drawings, 1 is the wagon-bod y, here shown as a box.

2 represents eyes whose shanks 3 are straps secured byscrews 4. preferably to the outside of the Wagon-body, as best seen in Fig. III, the shanks extending vertically upward from the eyes and serving the double purpose of strengthening the sides of the box-shaped body as well as firmly supporting the bottom.

5 represents the bottom sections, preferably beveled, as at 6 and 7, at their front and rear edges, so as to make a close joint when the bottom is closed, to which end the lower edge of the rear of the body is also beveled, as at 8, While the front edge 9 of the foremost section is not beveled, but engages with the inner face of the front of the body, as will be clear.

10 represents straps of metal extending across beneath the sections 5 and secured thereto by screws 11, each strap preferably standing in front of the center of its section,

whereby the preponderance of weight of the latter (with or without a load upon it) will tend to throw the sections to the dumped position. One end of each strap is journaled in one eye 2, as at 12, while the other end has a shoulder 13, beyond which it is journaled in the eye 2 at the opposite side of the body, and beyond that it is squared and reduced, as at 14, beyond which again it is further reduced and threaded, as at 15.

16 is a lever, one foreach strap, whose lower end has a squared opening fitting the squared portion 1 1 of the strap, and 17 is a nut engaging the threaded portion 15 outside the lever 16 to hold the latter in place.

18 is a side bar extending along one side of the body and pivotally connected, as by screws or bolts 19, with the upper ends of the various levers 16, and it will be clear that by movement of this side bar the levers will be turned in either direction and the bottom sections 5Wl11 be dumped or closed, as desired. When dumped, all the bevels stand in approximately vertical planes, so that there is practically no impediment of the free exit of the earth or other contents of the wagon. When closed, the bevels coact, so that there is practicallyno crack for the escape of such earth. The specific form of connection between the levers and the straps permits the removal of parts for repair or substitution when desired.

The means employed in the present case for moving the side bar consists of a handlever 20, which is either an extension of one of the levers 16, as in full lines in Fig. I, or is separately pivoted at 2i to the side of the body, as indicated in dotted lines in Fig. I, and at 22 to the front end of the side bar, and this lever moves over a rack-bar 23, with which it may be engaged to hold the bottom closed.

The parts are of the desired sizes, proportions, materials, and shapes, with the exception of the details above described.

In connection with the details of the dumping-wagon above described I use a lock for each individual section, whereby weight of that portion of the load which rests thereon will be positively supported, rather than having any one section locked and the others held closed through the instrumentality of the connection between the sections. This lock is best illustrated in Figs. I and IV, and in the present instance it is constructed as follows: 32 represents links, one for each end of each. section, each link being pivoted at its upper end to the wagon-body, as at 31, preferably beneath a clevis 34, and the lower ends of these links are connected in pairs by rods 33, which extend across beneath the wagon-body in proper positions to be adapted to be moved under the free or dumping edges of the sections 5 or to be moved out from under such edges, so as to allow the wagon to be dumped. By preference these rods 33 are rollers mounted loosely within the lower ends of the links 32, whereby they roll under the sections and along the lower edges of the sides of the wagon-body. While any suitable mechanism may be employed for swinging the various links simultaneously, I prefer to mount bars 25 loosely in grooves or recesses 26 in the outer faces of the sides of the wagon-body, which bars have pairs of pins or staples 27 in their outer faces at proper points loosely engaging the links, and the two bars are moved by a bail or handle 28, which preferably stands at one end of the Wagon-body and is pivoted at 29 to the sides thereof, while its lower end is pivoted, as at 30, to the bars. By this construction it is obvious that when the handle 28 is moved in the proper direction the two bars 25 will slide and the several links will swing and as they do so they will move the rods or rollers 33 out from under the free edges of the bottom sections 5, after which the latter may be dumped. After dumping, the sections are swung back into place and the rods are moved beneath them by a reverse movement of the handle 28. All parts of this look are of any suitable materials, and the details of construction may be varied to a considerable extent.

What is claimed as new is- 1. In a dumping-wagon, the combination with the body, eyes in pairs carried by the sides thereof, the bottom sections having their adjacent edges oppositely beveled, a strap secured beneath each section in front of its center and journaled in a pair of said eyes, and a shoulder at one end of each strap just inside the eye, said strap being squared outside its journal in this eye and reduced and threaded outside the squared portion; of a series of lovers having squared openings in their lower ends engaging the squared portions of the straps, nuts on the threaded portions of the straps outside the levers, a side bar pivotally connecting the upper ends of all the levers, a pivoted hand-lever connected with the side bar, and a rack-bar over which said hand-lever moves, all substan* tially as described and for the purpose set forth.

2. In a dumping-wagon, the combination with the body, the bottom sections pivotally supported thereby, and means for swinging them simultaneously on their pivots; of a lock for the sections comprising two links for each section pivoted at their upper ends to the outer faces of the wagon-body, rods conmeeting their lower ends in pairs and adapted to be moved beneath or out from under the free edges of the dumping-sections, two bars movable longitudinally in recesses in the wagon-body behind said links, pairs of pins in each bar loosely engaging each link, and a bail or handle pivoted to the body and to the bars for moving the latter simultaneously, all as and for the purpose set forth.

In testimony whereof I have hereunto subscribed my signature this the 18th day of May, A. D. 1901.
